Would it be wrong if I didn't text him back??

So me and this guy have been talking for about 2 weeks. He tends to reply late, and usually doesn't have anything interesting to say... Last night he texted me "What you're doing?" I replied, and he didn't even write back to me... So this morning he texted me "Good morning" like he does every morning... I didn't reply because I feel like this isn't going to go anywhere, I like him... but he seems so plain. So, would it be wrong to not reply to him?

He invited me to go to his house on Saturday night, around 11 or 12.. I guess he just wants sex... so I'm just going to try get over this. Thanks for all the advice guys, much appreciated. xoxo
